A low concentration receiver concept for cost effective crystalline back contact cells
2014
A versatile interconnection and receiver concept for back contact low concentrating crystalline solar cells is pre-sented. The key feature is the AP-C-MWT cell [1] which allows for any cell formats as a multiple of 22.5 × 10 mm 2 . We demon-strate the feasibility of an adequate receiver concept and show the electrical optimization steps for a given concentration. The steps include the electrical finite-element-method (FEM) simula-tion of the interconnector conductivity and an analytical model to derive the optimal geometric design. Finally measured efficiency data for a built prototype are reported, showing a receiver effi-ciency based on string area of 19.2% (C=9.9) and a cell to receiv-er efficiency of 99.3%
